Windows Vista problems and DVD

I got in trouble for awhile with my DVD RW
I can read and write the cdroms.  I can write on DVD without using any additional software but windows.  I can not read or read that DVD software or movies, including software to reinstall windows vista.
I asked here several times for help and decided to restore the computer to factory settings.
Then, I followed closely ALL the following:

Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
ends. Remove and replace, do not just tight. For laptops, you can often clean power and
contacts data with a pencil eraser.

Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
Playback of CD and DVD). Therefore, it is not unusual for 1 or 2 rooms with not so work that others do it properly.

Did you follow the Troubleshooting Guide for the reader who still does not work? There are some registry entries
that the troubleshooter does not, and those who "could" be the cause.

Check with your system manufacturer Maker and device for possible firmware updates and the good
Your player registry entries.

Here are the keys in my opinion, are those in question - for the reader of CD/DVD subkeys of course that he will be
other subkeys in these keys. Be sure to ask specific keys involved as well as the parameters.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

************************************************************************

For the first problem, I received the following message is displayed:

UNRESOLVED PROBLEM: MEDIA IN THE UNREADABLE CD/DVD DRIVE.  THE DRIVE IS EMPTY OR MEDIA MARKER NOT ACCEPTED.

I've updated the drivers without success, I deleted the drivers without success.

I am trying all the new ideas.

THX in advance

Remember that the drive is really 4 readers separated in parts of a case if some works do not
is not uncommon. Rob - bicycle - Mark Twain said it is good.
